Patented Dec. 29, 1931 JOSEPH B. SOLOMON, F OAKLAND, CALIFORNIA wmmwSAFETY Lock AppIication filed January 25,1930, Serial No. 423,372;

My invention relates to improvements'in 7 window safety locks, and'itconsists in the combinations, constructions and arrangements hereinafter described and claimed. In ofiicebuildings and inother types ofbuildings such as homes for the aged and insane asylums, someaneansshould be provided for permitting the window sashes to be opened aslight distance for allowing air to enter and leave the room, but thismeans should limit the opening of the window sashes so as to prevent aperson from accidentally stepping out through a window fully opened orfrom intentionally stepping out man attempt to commit suicide.

With the above objects in View, I have designed a window safety lockthat will permit' the upper and lower sashes to be moved a predetermineddistance and then be'prevented from further movement unless anauthorized person temporarily releases the locking me chanism to permitthe full opening of the win dow sashes; to permit the Window sashes tobe opened a L slight distance or a greater distance.

It should further be noted'thatfthe device is especially adapted for usein homes to prevent burglars from moving the sashes into knows thesecret combination.

Other objects and advantages will appear i as the specificationproceeds, and the novel features of the device will be particularlypointed out in the claimshereto annexed.

My invention is illustrated in the accompanying drawing, in which:

Figure 1 is a front elevation of a window showing my device operativelyapplied thereto,

Figure 2 is a Vertical section througha portion of the device, and

The device is adjustable so as Figure 3 is an enlarged view of a portionTo this window I securearod 4. that hasa number of recesses 5 thereinequally-spaced from each other. These recesses may be arranged closetogether if desired, or they may be separated from each other aconsiderable distance. i The rod .L'is received in a socket 6 that 111turn is secured to the window frame 1 and'in a second socket 7 that isalso secured to the window frame. The rod 4 is preferably disposedadjacent to one side-of the frame so as'n'ot to obstruct the view, butit is obvious that it may be placed indifferent positions other thanthat shownin Figure 1. Each window sashcarries an arm, and I havenumbered these-arms 8 and'9 respec tively. The arms have bores forslidably receiving the rod 4:, and carry rubber bumpers-10 and 11' for apurpose hereinafter-dc scribed. 1 I V fThe particular construction ofthe lock is shown in Figure 2. I provided two locks '12, one for eacharm 8 and 9, and these locks are adjustable on the rod 4: soasto-determine the amount of opening of the sashes 2 and 3. Referring toFigure 2, it will be noted l that the lock 12has a bore 13 therein forreceiving the rod 4. A spring-pressed locking pinl l is carriedby thelock '12 andis full open position after the sashes have been partlyopened. The device is extremelysimple in construction, and may bekey-actu-. ated or actuated by an authorized person who" designed toenter any, one ofthe. recesses 5.

Pins 15 guide the locking pin 14:, and a spring 16 urges the locking pininto the 'recess 5.

When the pin is received in the recess,'the lock 12 cannot be moved onthe rod 5.

I provide two means for releasing the looking pinl. I will firstdescribe the keycont-rolled means. -A gear 17 is mounted within the lock12 and meshes with a rack 18' formed onlthe locking pin 14. The gearandfreethe locking pin" 14 from the recess,

5. "The lock 12 maynow be moved into'any position desired, "and thefreeing of the key (not shown). will cause the spring 16 to again :tseat' thelocking pin. 14. in the recess 5. for

any desired place on the rod a.

r the arms abut the locks.

preventing further movement of the lock 12.

A manually controlled means is also provided for releasing the pin 14..At the bottom of the lock 12 I mount a collar 21 that is threaded uponthe lock 12. When this collar is released from the lock 12, an arm 22 isexposed. This arm is rigidly connected to the lockng pin 14 so that amanual movement of the arm to the left in Figure 2 will free the lockingpin from the recess. A spring clip 23 receives the arm 22 and yieldinglyholds it in place with the bolt 14 retracted so that the lock 1 may befreely moved along the rod. hen the lock is disposed in the desiredposition, the arm 22 is moved to the ight and is freed from the springclip 23. The collar 21 may now be screwed upon the lock 12 so as to hidethe arm 22.

The collar 21 carries a resilient bumper 24 that abuts the bumpers 10 or11 when the arms 8 or 9 are moved into engagement with the locks 12. Thebumpers prevent the shattering of the glass should too much force beused in raising the window sash.

Vhen the locking pin 14 is key-actuated, it also moves the arm 22,and'the arm is received in the spring clip 23 in the same man ner asalready described. This holds the locking pin 14: out of engagement withthe rod 4 until the key is again turned for freeing the arm 22 from thespring clip 23.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

The device may-be applied to any standard window, and the locks 12positioned in The locks permit the window sashes to be opened untilFurther movement is. prevented unless the lock is released from the arm4; by an authorized person who has a key or who has the knowledge of howto\ gain access to the arm 22.

Although I have shown and described one embodiment of my invention, itIS to be understood that the same is susceptible of various changes, andI reserve the right to employ such changes as may come within the scopeof the invention as claimed.

The lock can be replaced with a new one without inconvenience to anyone.

I claim:

1. A window safety lock comprising a rod having recesses therein, locksadjustable on said rod and having plungers removably receivable in therecesses, arms slidable on said rod and being secured to the windowsashes, said locks limiting the movement of the arms.

.2. A -window safety lock comprising a rod having recesses therein,locks adjustable on said rod and having plungers removably receivable inthe recesses, arms slidable on saidrod and being secured to the windowsashes, said locks limiting the movement of the arms, and resilientbumpers carried by said locks and arms for abutting each other when thearms are moved into contact with the locks.

3. A window safety lock comprising a casing having a bore for slidablyreceiving a rod having recesses therein, a spring pressed pin carried bysaid casing for entering the recesses, an arm carried by said pin formoving it, a collar normally covering the end of the arm and beingremovable from the casing for permitting the arm to be moved.

a. A- window safety lock comprising a casing having a bore for slidablyreceiving a rod having recesses therein, a spring pressed pin carried bysaid casing for entering the recesses, an arm carried by said pin forn1oving it, a collar normally coveringthe end of the arm and beingremovable from the casing for permitting the arm to be moved, and aspring clip for holding the arm and pin in retracted position.
